A device for automatically detecting axial and radial runout of shaft parts

Abstract

The invention discloses a device for automatically detecting the axial and radial runout of shaft parts, which includes a mounting panel for installing and fixing all devices; Alignment device, runout measuring device for measuring radial runout of shaft journal and axial runout of shaft shoulder, man-machine interaction device for collecting, displaying, analyzing, judging and storing runout detection data, It is used to install and fix the electrical control device for all electrical components in the detection mechanism, and the friction transmission device for transmitting the rotation of the motor shaft to the shaft parts; The combination of rods transmits the jumping error at different positions at the same time, which avoids the defect of multiple measuring points of the traditional pendulum meter and needs to adjust the detection instrument multiple times, and realizes the simultaneous detection of the error of three measuring points.

Description

technical field [0001] The invention relates to a runout error detection mechanism, in particular to an axial and radial bidirectional runout error automatic detection mechanism and device in mass production of shaft parts. Background technique [0002] As a key component in the transmission system, the accuracy of shaft parts has an important impact on the performance of the entire transmission system. The radial runout of the journal where the bearing is installed affects the rotation accuracy of the shaft, and the axial runout of the shaft shoulder affects the positioning accuracy of the parts installed on the shaft. In the actual production process, especially in mass production, the runout error must be strictly controlled by testing equipment. The size of the amount. [0003] For the runout error of parts, the CON1-152 concentricity measuring instrument of domestic steel company, the NTY-TZ-002 concentricity measuring instrument of Japanese Nititoyo company and the MM...

Problems solved by technology

However, in view of the high cost of measurement, long time and high requirements for operators, most manufacturers of shaft parts currently use deflection meters or their improved instruments to detect runout errors.

The pendulum meter has the advantages of low cost and simple operation, but at the same time, it also has the problems of low detection efficiency, full participation of operators in the detection process, and low measurement accuracy.
